To all whom it may concern;

Be it known that 1, WILLIAM GoonnLL, a citizen of the United States, residing at h lillinoclret, in the county of Penobscot and State of Maine, have invented certain new and useful Improvements in Partition Forming and Attaching lllachines of which the following a full clear, and exact de scription.

This invention relates to machines for operating on webs and with regard to certain more specific features thereof to devices for forming inserts for paper bags or boxes and applying the inserts in such manner as to hold fragile or perishable articles with in the bags or boxes and away from the side walls of the same.

The invention has for one of its objects "the automatic and rapid production of partitions suitably apertured and gummed, from a continuous paper roll or web, and the arrangement of the partitions in position to accept the bag.

Another object of the invention is to provide means of a reliably operative character adapted to act automatically to press the partitions against the side walls of the bag at a certain point in the cycle of operation of the partition forming mechanism whereby the partition or insert is caused to adhere at the gummed areas to inner surfaces of the bag.

Still another object resides in the provision of means for automatically gripping the formed partition while the bag is being applied and pressed, and for automatically releasing same after the pressing operation.

Qther objects will l in part obvious and in part particularly pointed out h reinafter.

The invention ac ordin ly consists in the various features of construction, combinais of elements and arrangements of parts iich will. be exemplified by the construction hereinafter set forth and the scope of the application of which will be indicated in the following claims.

Fig. 18 is a view corresponding to Fig. 3 showing the cutter and folder in operation.

To the end of fulfilling the above stated objects the embodiment of the invention shown in the drawings comprises a machine which is operative to automatically feed a section of paper web into position to be acted upon simultaneously by gumming and punching mechanism whereby opposite ends of the section are treated with adhesive and a plurality of apertures are formed in the body of the section. With the web section so formed and treated the machine gives a further step of feed to the web which urges the section into a position where it is severed in no )er length from the remainder of the web. acted upon by a folding device. and held in folded position by a gripping device while the bag is applied and a mechanism is operated to cause adherence of the section to the walls of the bag. Thereafter the gripper is released and the finished bag may be removed from the machine. During the period that the advanced section is being severed. folded, gripped, secured and released the forming and treating operations are in effect on the next web section. By this means the bag inserts may be rapidly produced and affixed by relatively unskilled operatives; there is no substantial waste of material, and the cost of production of the finished partitioned bag is relatively low. The method of partitioning bags in this manner so that articles such for example, as ice cream cones, may be held upright or away from the interior surfaces of the bag, is also a feature of the present invention.

Referring now more particularly to the drawings there is indicated at 10 the machine frame comprising standards 11, a table 12 and numerous fixed uprights and cross pieces having provision for supporting the working parts ofthe machine. From any suitable source. of power such as an electric motor, which may if desired, be arranged on the table 12, a shaft 13 is driven. This shaft is journaled in parallel uprights 14s and 15. of a supporting member or bracket 16 which latter is fixed to the table 12.. A pinion 17 fixed on the shaft 13 meshes with a gear 18 fixed on anintermediate shaft 19, the latter being journaled inthe extreme upper ends of the uprights 14. and 15 of bracket 16. Fixed on the intermediate shaft isa pinion 20 which meshes with a large spur gear 21 which latter is fixed upon whatmay be termed a main driving shaft 22 of the inachine.

The main drive shaft 22' has fixed thereon two intermittent gears or wheels 23 and 24: and a cam 25. The first of these gears is provided with diametricallyopposed toothed sections 30 and 31. intermittent rotation of a shaft 32 through the medium of a pinion 33 which is fixed on the shaft and which is rotated substantially one-halfa revolution by, each of the toothed sections of the gear or wheel 23. In a manher which will be more fully set forth hereinafterthe .punch mechanism is operated from this, intermittent gear or toothed wheel 23. H

Theintermittent gear or wheel 24 has a single toothed section 35 which operates periodically to rotate each of three shafts 36, 37 and 38 through pinions 39, a0 and 41 respectively. The shaft 36 controls the feed ofthe paper web. The shaft 37 controls the operation of the cutting mechanism, and the folder; and the shaft 38 operates the press- 4 ing mechanism.

Journaled in a standard 50is a webroll 51, the free end of which is passed between the feed rolls 52and- 53. The lower feed roll 52 has its shaft 54 journaled in slots in uprights 55v and 56. On one end of the shaft 54 is a gear 60'which is driven through a pinion 61 from the intermittently rotated shaft 36. On theopposite end of the feed roll shaft 54 there is a spur gear 62 which connects with a similar gear 63 on the shaft 64: of the upper feed roll 53. The direction of drive is as indicated by the arrows in Figs. .2, 5, 6, and 7 and the feed rolls are periodically rotated to urge the web a predetermined distance across a fixed shelf 70. A roller 71 shown in Fig. 3 above the feedroll 53 is merely for the purpose of insuring its continued engagementwith the lower feed roll.

A glue pot 72 is provided in suitably fixed relation with the frame and a glue roll 73, suitably journaled in the side walls of the pot, is continuously driven from the main drive shaft 22 through the gear 21, a pinion These two sections cause 7e, shaft 75 and the'chain and sprocket, worm and worm wheel connections shown in Fig. 1 of the drawing.

The and punching mechanism. "With a section of the web suitably dis- (See also Fig.

posed across the'shelf 70 and the web rolls formed thereon the eccentrics 82 and 83 which operate on circular punches 8e and 85.. These punches are secured 1n a block 86 which is apertured to {it slidablyon the uprights 80 and 81 and be guided by these uprights ina vertical reciprocatory movement effected by the rotation of the eccentrics. Spaced upwardly from the block 86 and connected thereto by means of four bolts 88 there is a lifting plate 87 which cooperates with the block to form a yoke for the eccentrics. Spaced downwardly from the block 86 is a presser plate and guide 90. This plate is held in spaced relation with the block by means of springs 91 and 92 arranged respectively about bolts 93 and 94. The lower ends of these bolts are tapped into the presser plate and their heads 95 and 96 determine the position of the presser plate when the punches are in their upposition.

A rock shaft 100 is journaled between front and rear uprights 101 and 102 of the frame superstructure as shown in Fig, 2 and on. it there are fixed two arms 103 and 104i spaced apart in the direction of feed of the web and carrying at their lower free ends loosely mounted disks 105 and 106 j ournaled in slots 10"? in the arms. During a prolonged portion of the cycle of operation of the machine these disks bear on the continuously rotating glue roll 7 3 and they are constantly supplied thereby with glue from the reservoir 72.

When the shaft 32 is rotated a half turn the ecentrics 82. and 83 are given a movement through 180 and the block 86 carrying the punches is urged downwardly. The presser plate 90 is'caused to bear upon the web to hold it securely in position. This plate is yieldable against the action of the springs 91 and 92 and the punch members 84 and 85 lot penetrate the die or fixed shelf 70 resulting V of the gear or wheel 2-1 becomes effective to rotate the shaft 7 to actuate a cross-head 110 mounted upon an upright beam 111. This cross head is reciprocated once during every revolution oi the main drive shaft by means of crank connection shown at 112 in Fig. 1. A lever 113 is loosely connected to the rear of the crosshead and extends upwardly above the frame of the machine where it has a pivotal. connection with an arm 11 1 extending from the rock shaft and keyed thereto. It will be seen, therefore, that reciprocation of the crosshead will affect the rocking of the shaft which in turn will cause the disks and 106 in suitably gummed condition, to roll over the web and return, thereby providing the web with gumined areas as indicated in Fig. 10 of the drawings.

The cutting, folding and oy-eating mechanism.

The movement of the cross-head which fects the operation of the gumming mechanism also controls the operation of a cutter (1 and a folder The cutter comprises aknite carried on a pair 01 parallel links 121 and 122 journaled in the frame structure. The lower link 121 has a pin and slot connection with the cross-head as indicated at 123 in Fig. 1. The shelf 70 has a front kniferein'forcing wall 12 suitably apertures at 125 to permit the feed of the web. As the cross-head moves downwardly the knife is carried downwardly with a slight sheering action due to the parallel link cut, the return of the cross-head carries the knit to a position above the aperture 125 thereby permitting a subsequent step feed of the web.

The folder 1? is of inverted ll shape comprising a reinforcing crutch at th lower end of a link 131. This link is pivotally connected to the parallel links and 133 which have their opposite ends pivotally connected to anuprightof the trame structure. The lower parallel link 182 of this mechanism is connected by a link 13% to the crosshead and a downward movement of the latter causes an arcuate down movement of the folder into position of contact with the web section that is being severed by the knife. The folder is given resiliency by means of a spring member and the opposite ends and 13'? of this spring member bridged by a band 188 of fabric or other pliable material. The continued movement of the cross-head causes the folder to urge the severed web portion about a parti. ion or anvil 110 which latter is upstanding from the table 12 of the frame. The machine is timed and the parts arranged so that the folder will pick up the severed web section at the instant that it is severed from the remainder of the web, and dispose it centrally about the partition 7 with the web section though a link 1532' 140. Before the folder releases, a pair oi: gripper fingers 141 and 1 12 are actuated t engage the opposite ends of the severed web portion on opposite sides the partition and hold the web section in folded position. The mechanism for actuating.- fle gripper lingers comprises a cam 25 driven. from the main operating shaL't't cam ates with a cam roll 152 at the upper end of a rod 158 mounted for vertical sliding mo ment in the frame. The rod at lower e has a pin and slot connection with 2. l 154 fixed on a rockshalt which lat i suitable bearings in the frame street. 1 Coil springs l. 6 are arranged between rame and the lower end oi the rod act to swing the lever 151 on the rock 11 to cause engagement oi the gripper links 158 and 159 which connect Ni-ill 0T1 3 )er tin -ere.

Assembling and pressing.

With the web section held by the ripper fingers the machine o; orator applies an inverted bag after the manner indicated in Fig. 8 of he drawings. The bag is held in this position by the operator r mg the latter part of the cycle of operation of themachine. The toothed section 85 ot the ear or wheel 24 then operates upon pinion presser controlling shaft 38 and Euro crank on the end of this the? sol li 171 a lever 172 is oscillated. 173 and 17 1 are journaled in the "lttiii rocked by means of love 172 and a connection 175 betvxeirsaid lever ant rock shaft 1'11. Pro a Operation.

The feed rolls being driven in opposite directions from the main driving shalt cause a predetermined amount of web to be fed 13o across the die shelf 70. The punch mechanism and gumming device are then operated in the manner hereinbefore set forth, The punches and prcsser plate remain in their downwardly actuated position during sub stantially one-half revolution of the main driving shaft. on the wheel 23 then operates the pinion 32 to further rotate theeccentrics to withdraw the punches and release the prcsser plate from the web. With the web section thus gummed and punched the machine starts on its second cycle of operation commencing by feeding predetermined length of web. During ihllS operation there is actuated a lifting rod 190 slidably mounted in the frame of the machine and having a finger 191 extending along the forward edge of the die shelf. This lifter is operated by means of a crank and lint: connection 192 the crank-being fixed on the end of the shaft 54 of the lower feed roll. The parts'are V timed so that as the feed movement of the I the first section.

web takes place the finger 191 of the lifter will advance forwardly and upwardly owto the incline of a slide bearing 193. Th function of this device is'to lift the forward edge of the web into a position. where its advance over the top of the partition. 140 will be insured 7 At the end of the second stroke of feed the punches again operated, the web be ing held as formerly by the presser plate and the punches in their penetrated positions. The cross-head 110 is then operated causing the web to be severed by the knife and simultaneously contacteo with by the folder and disposed about the partition 140. As the action of the glue rolls is also under control of the cross-head it will be seen that the second web section is being gumined during the severing and folding operations on The reciprocation of the cross-head is substantially rapid and the knife and folder are returned to their upper positions immediately the opposite ends of the web section have been gripped by the fingers 1&1 and 1-12. Thisenables the operator to apply the bag and as the main shaft continues its rotation the toothed section 35' of the gear wheel 24 engages with the pinion ll and operates the presser blocks 182 and 183 into and out of pressing engagement. 7 v 7 At a convenient point in the operation of the machine the second toothed section of the gear 23 operates through the pinion 83 and shaft 32 to rotate the eccentrics 82 and 83 another half turn, causing withdrawals of the punches and the lifting of the presser plate 90. in the present embodiment of the invention this lifting operation takes place just prior to the actuationbf the presser blocks. The punches are provided with gravity strippers 1 50.

The second toothed section Asmany changes could be made in the above construction and as many apparently widely different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter set forth in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
